Oxygen Not Included: Klei space colony sim

This thread made me curious about how much water you’d need to keep back one atmosphere of air pressure. This game really does make one consult wikis.

So each tile is, say, 3m. Four tiles should do it. It would be interesting if the game had pressure in its physics. It would add a new layer of disaster possibilities.

I haven’t had to worry about perfect airlock since I have gotten to the point where I’ve visited space biomes. But a double airlock with a few spaces works well enough it seems. Even when the other room is Natural Gas Geyser with pressure of 5KG/tile.

Any recommendations for survival vs no sweat for my first real game? Does no sweat make ti too easy to choices don’t have many consequences?

I gotta go with survival. The challenge level isn’t real high to begin with, and the game keeps a long autosave history should you discover something you did earlier has had unfortunate consequences.

Agree with @Thrag.

I’m slowly making progress - cycle 15 or so. It took me awhile to figure out how to deal with the CO2 problem.

Definitely survival for me - I feel aimless if just tinkering in sandbox without the pressure of the systems.

I’ve been playing my survival game, up to cycle 27. I’m definitely feeling like I’m progressing more slowly than intended, but I’ve had a bunch of fun getting to the point I am now.I am starting to feel a bit lost because I don’t have any obvious thing to try for. I guess I’m supposed to escape this place, so going up is probably a good idea.

The first things I did was to get a water supply (pitcher pump), an outhouse and wash basin. After a rough night of sleep, I figured I should get them some cots. They lived off of their rations until they started making their mushbars.

Then I started researching so I needed some power. Manual generator and a couple small batteries sufficed.I’m having a hard time getting them off the mush. I have 6 seeds of the rice things growing that I can use, but they are more of a treat than a staple. Got a compost pile going for my polluted dirt.

The oxygen ore stuff lasted a while, but eventually I added some oxygen diffusers. Kept hitting max pressure. After mucking around a while I got my carbon scrubbers working. For the longest time I didn’t realize I needed a pump for the water intake and the special pipe end to be able to drain the polluted water.

Then I cleared a nice place for them to eat and gave them tables, decorated their bedroom with crown molding. Added a super computer.

I needed some more power so the coal generator was added and upgraded to jumbo batteries. With the extra power I added some lighting, electric grill (although I still don’t have a lot of options for better food). Outhouses changed over to lavatories and washbasins to sinks. Oh, and added some refrigeration for food.

But, without some focus I’m losing steam - not sure how much longer it will hold my attention, but like I said a lot of fun up to this point.

You have no idea what problems you created yet. That used to be what got you.

What you are using is consuming water and dirt at a fast clip. Dirt is finite (so far) and water too (until you find / make a replacement loop). So, you’re gonna die if you don’t know more, you just don’t know it yet.

And a carbon scrubber inside the starting dome? As well as the research stations. At least the batteries are small. So, you are in a race you don’t realize. Do they get more food/options before the heat gets too hot for those options to be viable? Do they run out of water before they finish researching those options? Do they starve?

You are also probably making oxygen using algae. Also finite (for now). So you are also going to suffocate unless you find more algae or replacement oxygen source soon. One of your best replacement options takes … water … which you still haven’t found out how to replace yet. So …

You have started the race conditions of no oxygen, no water, no dirt, no algae, no food … all related. You just don’t realize you’re dead yet unless you progress. Which makes heat, which will also kill you (but your food first). Or you can stop now and bask in the glow of having survived the crash landing. :)

Oh I make no pretenses that I’m playing well or know what I’m doing :-)

Oh sorry, nothing to do with your competence (or lack)! That is sort of how the game progression is through middle.

Do obvious/only solution, which creates problems that reveal themselves. Fix problems with new items/new systems. Which in turn create even more new problems … fix … repeat.

No offense taken! :-)

I’ve got a pipe blockage but can’t figure out where it is. I look at the overlay, everything is connected. It was working fine. Not sure what the deal is.

I can see where the pipe stops containing water. I don’t see any reason. I deconstructed it and rebuilt that section of pipe and no luck.

Usually that happens when there is a mix of inputs and outputs on the same line so the flow doesn’t have a single definite direction. If the pipe loops onto itself this will also happen. Use bridges to force the flow in a given direction where there is confusion.

In addition to being one way valves, bridges are also useful to take advantage of the nature of inputs and outputs. Inputs will take as much as they can out of a pipe. Meaning that until an input backs up it will take the full capacity of the pipe/vent anything past the input will get nothing. Outputs will only output if the is room in the pipe.

Flow going into a T intersection in a pipe will alternate. But replace the pipe coming off the T with a bridge and as long as the pipe connected to the output of the bridge is flowing nothing will ever make it past the bridge’s input to the other side of the T. Similarly if flow through two pipes merges in a T the flow will alternate. If one of the pipes connects via a bridge instead of a T, the only with the bridge will only flow if the other pipe stops flowing and presents the output with space to fill.

I got rid of a bridge intersecting off my main pipe and the blockage went away. Thanks!

I had the same problem when I switched water sources and left an old unused pump connected. The additional input blocked the pipe, even though it was an extra dead end and should have done nothing.

The fluid dynamics in ONI can be very confusing, at least to me. If in doubt, just add a bridge, they are one way and force the routing where you want it to go.

They put out a new update and patch.
They added a lot of new ways of raising morale like a mechanical surfboard and Juicers

The patch is nice mostly for bug fixes.

The recreation options are all cool or cute, but not even close to necessary on a standard settings run. High morale is trivial pretty quickly. On my next game I think I’ll try cranking up morale and disease difficulty, since those two systems are very rarely binding constraints.

Klei gave out info on their first DLC package.

Radiation threats and usage.

Space system overhauled. Space travel easier. Every destination is a separate ingame asteroid which you can found a colony on. Multiple specialized settlements on different asteroids make up your whole civilization.

Lots of minor added content promised both in the DLC and for the DLC-less base version.

This game is so incredibly good. Can’t wait for the DLC.
